Ythelllnited States, residin at Nqu,=,-,Yorltin}the county and State of ew i,Yqrl"ilfareinvented a. new and useful-Vacus fis] .taining the contents inv the condinon;

customary to make an outer and an inner` bottle iyith a vacuum between them, and mutually support the two bottles by a plurality of asbestos blocks annularly disposed between the same. Whilel asbestos is in general non-heat-conducting, yet, in fact'it willconvey heat much more rapidlyY than a vacuum; and it is desirable to eliminate as many of these supports 4as possible. In this invention I use but a single support, but so disposed that the bottles are mutually sul plorted whether standing upright or lying on t 1e side.

My invention is illustrated in the accompanying drawing in which- Figure 1, is a vertical section of a bottle constructed according to my invention; `and Fig. 2, is a horizontal section thereof.

In the accompanying drawing", like numerf als of reference referto the same parts in cach of the views; and 1n practlceI provide a bottle comprising t-Wo parts, or bottles fused together, the outer part being indicated by 3, and the inner by 4, and the two being fused together at the lip 5, to make an integral Whole, While the sealedshort tube 6, on the part 3, may be used to admit the silvering solution by which the inner surface of the part 3, is given a silver, or mercury coat 7, and the outer surface of the part 4, is viven a. coat 8, in any well known manner. he `tube 6, ma also be used in exhaustin .the air in ereatlng o. vacuum, but

VACUUM-INSULATED BOTTLE.

; is an easy matterto form additional tents,

or short tubes on the part 3.

Asdhe only cfpmecting part between the linner and outer parts of the bottle is the fused part orA lip when the inner `part is filled with a liquid, there y-will be considerbottles very shol'tlived. "llo avoidthis strain,

and, yet reduce .the mutual lsupport to the smallest possible limit, I provide yasma'll, piece of asbestos tubing, ,proportioned in length Vto the distance between. thefparts 3,'

ande, and which I prefer to mount on a small lug 10, which may be connected with the part 4 by attachin,f ,1r a small piece'of glass" i thereto, and is preferably of such a size that the asbestos tube 9 will be held thereon by friction until the part 3 is connected underneath the same; and while the bott-om of the part 3 is hot, I prefer to force a portion of the same into the lower end of the tube 9, as shown at l1, while the glass around the part 1]. is forced into suchV close contact with the bottom of the tube 9, that the said tube will mutually support and steady the parts 3, and 4 in every direction, the lug 10, and

part 11 assisting in the bracing, as will be understood. The support 9 is located between the bases of the inner and outer parts and by preference `at their common axis where it is most remote from the connection at the lip, thereby separating the support as far as ossible from the fused connection,

and gaming,r the best results in the mutual bracing effect.

It will thus be seen that I am able to mutually brace the inner and outer parts of the vacuum bottle with a single support, and leave the rest of the surface to be coated with the silvering solution; and as the silvering of the bottles makes them much more effective in resisting the radiation of heat, the more' of the surface coated, the better will the contents of the bottle be preserved in the condition desired. Then, too, as stated above, the vacuum between the parts affords much better insulation than asbestos, hencethe fewer asbestos supports, the less radiation of heat. I may also provide a casing 12, of any desired construction, to inclose the bottle.

Having thus described my invention, what fether at the I :claim as new and desire to secure by Let. tere Patent is- 1. A.. vacuum insulated bottlecomprising an inner part and an outer port joined tother having 1a.V vacuumjbetween them said mner part lhaving u lug, or projection on the base thereof, an asbestos tube mounted on said 111g, and the outei` part havin the bei; thereof bearing against lthe end o seid tu 2. A vacuum insulated bottle comprising un inner part und an outer part joined telip, said inner part having au orprojection on the base thereof, an as `tube mounted on seid lug, and the outer part having the base thereof bem-ing against the end of said tube with n portion thereof projecting within ,the tube.

3. A vacuum insulated bottle comprising an inner part and get'her ut the-lip und 9. tube mounted between the buses o said parts, Suid outer piu-t having n portion thereof projecting within the bottom of said tube.

4. A heut insulated bottle comprising two walis having u vacuum sp'uce between them. und a tube mounted between the buses of `thereof rojectin within said ineu l' whereby the latter un outer part joined tothe nella, the outer wail bovini; portion tu ted bottle comprisi between 5.A eat two welle having a' vacuum space between thewells, 4eueh inge. portion'thereof projecting' into said tu 6.
